Dennis Savarese Sent: 28 February 2007 04:01 AM Subject: Re: Yak-List: Re: White Paper on Russian Generator System Rob, As you have said, schematically it is virtually impossible for that to happen. In fact, on my personal airplane (52) I have left the battery/external power switch down for days at a time and did not have any discharging of the aircraft battery. So whatever is causing it is not reflected in the electrical schematics.

Robert Mortara, my emails to you are all coming back to me. : The user does not accept email in non-Western (non-Latin) character sets. Whazatmean??? I need to know what your dead line for the ad. Doug Sapp ________________________________ Message 3 _____________________________________ Time: 05:31:12 PM PST US Subject: Yak-List: Battery discharge: was White Paper on Russian Generator Syst From: "Rob Rowe" Dennis, Jorgen Thanks ... spoke to a couple of other UK based owners today ... one owns a -52 & could not comment (had not left the master down yet), the other a owns a -50 and had discharged the battery in this manner. So no obvious pattern here (if there is one anyway) ... so would like to ask the Yak-List if anyone else has experienced this issue to post a one-line message giving their aircraft model & year of manufacture please. If there are no others then I guess it's just coincidental.
